What changed in Rails this year?

Since Kamal 2 can host multiple sites on the same server, I am consolidating my apps into larger hosts so I have less servers to worry about. Most of my apps are Rails apps, but I have a few static jekyll sites like this blog and I decided to look into how could I move this site to a server I host other Rails apps on.

Someone asked on Twitter yesterday about the how to add TailwindCSS to a Rails 8 project the easiest way and having hot reload. This is how I believe it is to do so in a few minutes.

2 weeks ago, at the last day of Rails World, Sahil, the founder of Gumroad made a tweet, stating that Rails is a legacy framework, and announced that their are rewriting Gumroad in TypeScript for a few reasons. One was to get rid of the technical debt. It is a very weird take, because you will end up with the same technical debt after a while...

Kamal 2 was released recently and it brings a few singnificant changes. Traefik is replaced by kamal-proxy, Kamal runs all containers in a custom Docker network and secrets are passed differently to new containers. All these changes mean that the upgrade is not simple, but in this article I will walk you through an example to help with the process.

I had the privilege to attend and speak at Rails World 2024 in Toronto.
